Enterprises of any sizes rely heavily on their networks to function efficiently. From communication and collaboration to data storage and analysis, a well-optimised network is essential for success. But what exactly does network performance mean, and why is it so crucial for businesses?

Understanding network performance

Network performance refers to the quality and effectiveness of a network system. It involves evaluating and reviewing the speed, connectivity, reliability, and efficiency with which data is transmitted across a network. High-performing enterprise networks provide a seamless user experience by minimising delays, errors, and security risks while ensuring reliable high volume data transfer.

Key factors influencing network performance include latency, bandwidth, network traffic, network configuration, physical infrastructure, network security, environmental factors, and service provider.

Key network performance metrics

  • Bandwidth: Network bandwidth refers to the maximum amount of data that can be transmitted over a network connection within a given period. Bandwidth is measured in bits per second (bps) or in powers of ten of bits per second e.g. kbps, Mbps, Gbps or Tbps.
  • Latency: Network latency is effectively the network’s reaction time in terms of delivering data. It represents the delay between a request being made and the response being received. Latency is measured in milliseconds.
  • Throughput: Network throughput is the actual quantity of data that is successfully transferred from one point to another over a given period. Throughput is measured like network bandwidth.
  • Packet loss: The rate at which data packets are lost during transmission from one destination to another. Packet loss is provided in percentage as the quotient of number of last packets divided by the total number of packets sent.
  • Error rate: Measures the frequency of errors in data transmission in terms of bits, packets, frames or symbols. The bit error rate for example is a natural number representing the quotient of the number of error bits divided by the total number of bits transmitted.
  • Jitter: The variation in delay experienced by data packets. Jitter is measured in milliseconds.

Why is an optimised network performance important?

An optimised network performance is essential for several reasons.

It enhances productivity by enabling employees to work efficiently without interruptions caused by slow or unreliable connections. This reduces downtime and increases overall productivity.

For businesses that rely on online interactions, a well-optimised network is crucial for providing a positive customer experience. A sluggish or unreliable network can negatively impact customer satisfaction.

Network optimisation helps prevent security breaches by ensuring that data is transmitted securely and efficiently. This protects sensitive information from unauthorised access.

As businesses grow and evolve, their network needs may change. An optimised network can easily adapt to these changes, ensuring that the business remains agile and efficient. A poorly optimised network can lead to increased costs due to downtime, lost productivity, and security breaches.

By optimising network performance, businesses can reduce these costs and improve their overall profitability.

Key components of optimised network performance

To achieve optimal network performance, businesses must focus on several key areas:

  • Network Infrastructure: This includes the physical components of the network, such as cables, routers, switches, and firewalls. Ensuring that the infrastructure is up-to-date and well-maintained is essential.
  • Network Design: The network design should be carefully planned to meet the specific needs of the business. Factors such as traffic patterns, security requirements, and scalability should be considered.
  • Network Monitoring: Regular monitoring of the network allows businesses to identify and address potential issues before they impact operations.
  • Network Security: Implementing robust security measures, such as segmentation, firewalls, intrusion detection systems, and access controls, is crucial to protecting sensitive data.
  • Cloud Integration: Leveraging cloud-based services can enhance network flexibility and scalability, allowing businesses to adapt to changing needs.

Best practices for optimising network performance

Regular network assessment and monitoring

Conduct regular network assessments to identify bottlenecks, vulnerabilities, and areas for improvement. This should focus on performance metrics, security assessment, infrastructure assessment, and user experience monitoring. Network monitoring tools help to track performance metrics, identify potential issues, and proactively address problems.

Invest in high-quality hardware and infrastructure

Regularly upgrading and maintaining network hardware components like routers and switches is essential for ensuring optimal network performance. By keeping the network infrastructure current, organisations can benefit from higher data transfer rates and improved compatibility with the latest technologies.

Ensure network security

To mitigate cybersecurity threats, avoid disruptions and data breaches, your optimisation strategy must prioritise strong security measures against both internal and external threats. Key network security components include Distributed Denial of Service (DDoS) detection, protection, and mitigation. Implementing firewalls, intrusion detection systems (IDS), and conducting regular security audits, vulnerability assessments, and penetration testing provides comprehensive protection. A secure network does not only protect organisations form unauthorized access but also acts is a sensitive sensor for secure breaches or malicious traffic caused between infected endpoints or unsecure internet connections.

Network segmentation

Divide your physical network into virtually smaller, isolated segments to improve performance and security. By controlling traffic flow between segments, critical applications get dedicated resources, reducing congestion and latency. This targeted allocation enhances overall network efficiency. Additionally, segmentation limits the spread of cyber threats, protecting the network and maintaining consistent performance. Ideally segmentation is done automatically by the network based on security policies.

Bandwidth management techniques

Bandwidth management techniques, including Quality of Service (QoS) policies and traffic shaping, help manage your network resources effectively. Prioritise critical applications and traffic to ensure they receive the necessary resources for optimal performance. This is specifically relevant for wide area connections but may also apply in local networks.

Cloud-based solutions

Cloud services offer scalable resources that adjust to your organisation’s demands, ensuring consistent performance during peak usage times. With the flexibility to allocate bandwidth as needed, cloud platforms ensure smooth performance during peak times. Additionally, cloud providers offer built-in redundancy and global distribution, enhancing reliability and reducing latency.

Conclusion

Optimised network performance is not just a technical necessity—it’s a strategic advantage. By focusing on network performance, security, flexibility, scalability, and efficiency, your business can improve productivity, enhance customer experience, and drive growth.

Implementing best practices like regular audits, investing in quality hardware, prioritising security, and leveraging cloud solutions can significantly improve your network performance. However, achieving and maintaining optimal network performance is an ongoing process that requires expertise and dedication.
